Blizzard’s highly anticipated card game Hearthstone: Heroes of Warcraft has now officially entered open beta in North America, and is due to arrive in other “main regions” over the next few days.

Players who live in the United States and Canada can now download the beta without a key from Battle.net. “What if you don’t play in the North American region? Don’t worry,” the developer wrote. “We plan to go to Open Beta in all our other regions within the next few days, so stay tuned for more information!

“Open Beta is still not a final release, and we will be closely monitoring many aspects of the game to ensure a positive play experience for everyone,” Blizzard added.

“Please be aware that if smoke starts curling out of our servers due to unexpectedly high demand for Hearthstone, we may have to temporarily disable Open Beta account activations until we’re ready to take on more players.”

Matthew Bennett finally got his big break with EGM three years ago, following years of volunteer work for various sites. An ability to go many hours without sleep and a quick wit make him ideal for his role as associate editor at EGMNOW.com. He often thinks back to the days when the very idea of this career seemed like nothing but an impossible dream. Follow him on Twitter @mattyjb89. Meet the rest of the crew.
